I agree. . . creatively, use what you like, trend or no trend! I was just thinking the other day that chevrons will probably stick around - it's not like they're a new "invention"
I'm enjoying stripes, myself - another classic.
With home, fashion and papercrafting trends, it's one thing to notice them, consider them, be inspired by them. . and another to be ruled by them. For instance, if Asian style stamps suddenly became popular, I could see implementing certain elements because I was inspired, but I'm not going out and purchasing stamps, paper, etc., just to keep up.
